[aprssig] SSn-N Coordination

The T2 digi from argentdata can support multiple (7??) digi aliases.  It
also supports preemptive digipeating, which I suppose could be used to
bridge a packet inward from PA to CPA and WPA to CPA if you really needed
the traffic in your area.

I'm not familiar with the capabilities of byonics stuff....

The kantronics TNC can only support two aliases.

You could program a digi to respond to both PA and WPA.  I know the
population density varies dramatically from the southeast corner to the
west, but I just can't understand segmenting the state.
